Update to the new laws, this is for home builds only although a lot of this does apply to home build that use drosed lowers, receivers and frames, the intent is to clarify a boat load of incorrect information floating around. I'm just posting this as a what you have to do by when to make it easy.

1. You must complete a non featureless build by midnight Dec. 31 2016, This is the possession aspect of SB880 and AB1135

2. If you do not complete your build by midnight Dec. 31 2016 it needs to be a featurelss configuration.

3. There is no requirment to self register. Read that again THERE IS NO REQUIREMENT TO SELF REGISTER AT THIS TIME

4. If you decide to keep your firearm in an Assault weapon configuration you will then be required to register it as an Assault weapon.

5. You will then have until Jan 1 2018 to register as an Assault weapon. No pre registration is required.

3. If you do not properly mark your firearm by July 2018 you will be required to request a serial number from the state DOJ, they will then ask to see photographic evidence that you did in fact engrave the firearm as required, and pay a fee and your firearm will be registered.

4. After july 2018 if you desire to build a new 80% firearm you will be required to submit a request and a fee to build. Keep in mind this can be denied at anythime.

So here are the steps to take.

1. Build Featurless.

2. Properly mark your firearm

3. Enjoy what little freedom you have left in this state.

The first section is on 922.r Home build or Modify Compliance. This regulation only applies to rifles and shotguns. Handguns are Exempt from these regulations and may be build with any combination of import and US made parts so long as Federal Firearms laws, State regulations and local regulations are followed and met.

Chapter 18 USC 922.r

Section 922 Paragraph R states:

"It shall be unlawful for any person to assemble from imported parts any semiautomatic rifle or any shotgun which is identical to any rifle or shotgun prohibited from importation under section 925(d)(3) of this chapter as not being particularly suitable for or readily adaptable to sporting purposes except that this subsection shall not apply to--

(1) the assembly of any such rifle or shotgun for sale or distribution by a licensed manufacturer to the United States or any department or agency thereof or to any State or any department, agency, or political subdivision thereof; or

the assembly of any such rifle or shotgun for the purposes of testing or experimentation authorized by the Attorney General. "

- Muzzle device/attachment (to include a threaded barrel capable of receiving a device)

- Bayonet lugs

If your rifle or shotgun incorporates those features, it no longer is considered "suitable for sporting purposes".

Chapter 27 USC 478.39 defines the total number of parts allowed to be used in a imported build

No person shall assemble a semiautomatic rifle or any shotgun using more than 10 of the imported parts listed in paragraph (c) of this section if the assembled firearm is prohibited from importation under section 925(d)(3) as not being particularly suitable for or readily adaptable to sporting purposes.

Paragraph (C) defines the following parts as "countable" under the law:

This link is documentation that 922r compliance is the responsibility of the importer and/or builder. It also outlines that parts need not be marked with their country of origin.

California Assault weapons guides

It is up to you to know and follow the law. The old adage of ignorance is no excuse applies here like never before. Possession of a unregistered Assault weapon in the state of California is a felony. The last registration period closed in 2006, There is no grace period, there is no way to legally take possession of a listed weapon after March 31, 1992 for the Roberti,Roos AW ban, December 31, 2000. for the Characteristic/ features ban PC 30510, January 23, 2001 for AK/AR series weapons, And April 30, 2006 for weapons capable of chambering the .50 BMG cartridge. Do not try to side step these laws in any way as the Ca DA’s office is well known to be very aggressive on gun issues. They have been known to put unbelievable effort behind getting a conviction. DO NOT RISK IT. That said CURRENTLY everything is subject to change and as of right now the assault weapons laws are in a state of flux and will not be 100% clear on what is required for registration at this time. do your home work with current laws.
